Undocumented immigrants’ reluctance to file taxes could cost U.S. up to $479 billion, experts say

A hidden tax worry grows

Tax season usually sounds like paperwork, refunds, and deadlines. This year, experts say fear among undocumented workers may also affect how much money the United States collects.

Analysts warn that fewer filings could mean major revenue losses over time. The concern is not only immigration policy, but also the trust that keeps voluntary tax compliance working.

Why filing taxes matters

Many undocumented workers still pay taxes through paycheck withholding, sales taxes, rent, and tax returns. Some use Individual Taxpayer Identification Numbers instead of Social Security numbers.

Those payments help fund federal, state, and local services across the country. When people stop filing, the effect can reach budgets that support roads, schools, health care, and public programs.

The biggest estimate is huge

Yale’s The Budget Lab estimated that reduced tax compliance tied to IRS and immigration data sharing could cost $313 billion from 2026 through 2035 overall in federal taxes.

The group gave a wider range of $147 billion to $479 billion because taxpayer behavior is hard to predict. That top number is why experts are sounding alarms.

A large tax base is involved

The Institute on Taxation and Economic Policy estimated that undocumented immigrants paid $96.7 billion in federal, state, and local taxes in 2022 alone across the country.

That total included $59.4 billion to the federal government and $37.3 billion to states and localities. Those numbers show why filing decisions matter for public revenue each year nationally.

Trust keeps the system working

The United States tax system depends heavily on people reporting income voluntarily. If workers fear that tax records can bring immigration trouble, that trust can weaken quickly.

Experts say even small drops in compliance can be expensive for public budgets. The issue is not just one filing season, because habits can change when people feel unsafe.

Data sharing changed the mood

Tax professionals told reporters that the IRS-DHS data-sharing agreement made many undocumented clients nervous about filing returns this year across the country.

Even as the policy has faced court challenges and restrictions, the fear has remained across communities. For some families, filing taxes may no longer feel like a safe routine today.

Tax preparers saw fewer clients

Some tax advisers reported sharp declines among immigrant clients during the filing season. Daisy Schmidt, a Virginia tax adviser, said she lost up to 75% of her clientele.

Another adviser serving Maryland and Virginia said 30% to 40% of his clients did not file during tax season. Those reports show how fear may change behavior.

Tax credits changed incentives

The loss of some tax benefits also reduced the reason some families file this year. Advisers pointed to child tax credit changes affecting parents without legal status.

Even when children are United States citizens, some parents may no longer see the same financial benefit from filing. That can weaken another link to the tax system.

Little-known fact: Nearly 12.5 million U.S. citizens live with at least one undocumented or temporarily protected immigrant in their household.

Payroll taxes are a key piece

Many undocumented workers pay payroll taxes that support Social Security, Medicare, and unemployment insurance. ITEP estimated that those social insurance taxes totaled $33.9 billion in 2022 across the country.

These workers are barred from many benefits connected to those programs because of their immigration status. That makes their tax role larger than many people may realize today.

Every million people matters

ITEP estimated that for every 1 million undocumented immigrants living in the country, public services received about $8.9 billion in added tax revenue in 2022.

That figure helps explain why a drop in filings could matter beyond individual households. Cities, states, and federal agencies can all feel changes in tax collections over time across public budgets.

A wider fiscal debate follows

A Cato Institute study found immigrants paid more in taxes than they received in government benefits every year from 1994 through 2023 across government levels and communities.

The study estimated immigrants generated nearly $10.6 trillion more in tax revenue than related government spending over that period. Supporters cite that research in the current debate nationwide.

The exact loss is uncertain

There is no official federal count yet showing how many undocumented workers skipped filing this year. Researchers are working with estimates, reports, and past compliance patterns.

That uncertainty is important, but it does not erase the warning for budget planners. A smaller filing base could reduce revenue while making future tax planning harder for officials.

A tax debate with real stakes

The warning over possible lost revenue shows how immigration enforcement and tax collection can collide. When people avoid filing, the effects can spread across public budgets nationwide.

Experts say the next few years will show whether fear changes long-term tax habits. For now, the issue centers on trust, revenue, and federal policy choices nationwide.
